winterizing yamaha FX140

[baller44]

I have a 2003 yamaha FX140 and was wondering what i need to do to get it ready for the winter?? I lived in So Cal last winter so it really wasn't a concern for me, but now I have to go through a winter and have no clue on what to do. If anyone has any advise, please let me know.

Re: winterizing yamaha FX140

If you need any other information let me know. I have two FX140's and have winterized both of mine with no problems. They both have about 65 hours on them with only a couple of issues like too much oil from the dealer on one and a little rock problem that I'm correcting by replacing the impeller with a Solas 12/18. The only other problem I had this summer was they use a lot of gas :emoticons

I posted some of the stuff I did last winter on this thread:

Re: winterizing yamaha FX140

That thead on PWC Today has a couple really bad flaws. First, you can not run it out of the water for more than 5 min. Any longer can overheat the pump bearings - the thread says 20. 2nd, you can not run the motor without a hose connection for more than 5 seconds MAX, the thread says 10, multiple times for fogging oil down the intake. Third, it does not take 20 minutes for stabilized fuel to reach the engine.


It's real simple. Add stabil to the fuel - it only takes a few min during a normal flush to reach the injectors. Put it on the hose to do a normal flush, add antifreeze if you really want to - Yamaha does NOT require it. After a normal 5 minute flush remove the spark plugs and spray fogging oil down the plug holes, then just bump the motor over a couple times to distribute. 4's do not require fogging the intakes - these are NOT 2 strokes people. Snug the plugs back up, clean out any water, hit the gnine with WD-40.

I have two 2005 FXHO and will be winterizing them myself. After asking this question myself and listening to everyone answers. I wnet back to the dealer and they said to follow the Operating manual for "long period of non-use."

This is typically found in the "maintenance section." Mine is located on page 4-3.

It states the following (I summarized a little)

1. flush the system with water with the hose connection for 3 minutes while idling (DO NOT LET THE WATER RUN WITHOUT THE ENGINE RUNNING). After 3 minutes turn off water and force remaining water by squeezing and releasing the throttle lever for 10 to 15 sec. (special note states DO NOT run engine for more than 15 sec without water running through engine)

2. STOP Engine

3. Remove Air filter cover and air filter

4. Spray rust inhibitor (Yamaha Stor-Rite Engine Fogging Oil) in to each intake opening for 3 Sec.

5. Install air filter and air filter cover

6. Start engine and let run at idle for 15 sec (special note states DO NOT run engine for more than 15 sec without water running through engine)

7. Lubricate all cables, etc

8. fill gas tank and use gas stabilizer, drain all water in engine compartment (if any)

9. Wash & wax, remove battery etc.

The Yamaha directions do not make sense to me because within 15 sec you will burn out the fogging oil in the cylinders. So I think I will go with the idea of spraying the fogging oil in the cylinder directly and “turning over the engine” so the fogging oil will coat the cylinder walls and rings. I'm sure it will smoke in the spring when I start them up for the first time. But at least the piston and rings shouldn't be stuck to the cylinder wall.


This is just my 2cents.

Re: winterizing yamaha FX140

Well maybe you have some other information which is fine but I talked to my Yamaha dealer and here are there responses:

That thead on PWC Today has a couple really bad flaws.

First, you can not run it out of the water for more than 5 min. Any longer can overheat the pump bearings - the thread says 20.

There is no limit while running on the hose. I would rather ride it one more time anyway and add stabilizer the last 20 minutes while riding.

2nd, you can not run the motor without a hose connection for more than 5 seconds MAX, the thread says 10, multiple times for fogging oil down the intake.

Owners manual page 4.1 says 15 seconds max or it may overheat

Third, it does not take 20 minutes for stabilized fuel to reach the engine.

I agree it doesn't take that long

It's real simple. Add stabil to the fuel - it only takes a few min during a normal flush to reach the injectors. Put it on the hose to do a normal flush, add antifreeze if you really want to - Yamaha does NOT require it.

Did not know I didn't need anti-freeze. Is that still true way up north where is gets really cold? Does bliping the throttle get all the water out that could cause damage?

After a normal 5 minute flush remove the spark plugs and spray fogging oil down the plug holes, then just bump the motor over a couple times to distribute. 4's do not require fogging the intakes - these are NOT 2 strokes people. Snug the plugs back up, clean out any water, hit the gnine with WD-40.

When you say bump the engine over do you mean hit the starter but don't let it start?

Re: winterizing yamaha FX140

There is a 5 min limit on the hose, if you don't believe me that's fine - but I know otherwise. Search the forums for cooked seal carriers and bearings.

I'm 99% sure the 'no cooling' limit is 5 seconds in the service manual but I might be wrong - I'll take your word for what the Owner's Manual says. Either way that's a small point.

Sea-Doo's have different cooling passages and require anti-freeze, as there are many pockets that do not drain. Other brands do not have that problem and have never needed anti-freeze, period.

Yes bump over means turn over without starting.

I lived in Michigan for 25 years, I know how to winterize my skis. Yes I have an FX140 too.

Re: winterizing yamaha FX140

Just type in "Winterizing" in the search and see how many threads come up! If you want to get an idea of what most people do or have asked.

Re: winterizing yamaha FX140

We have warm winters here so I don't have to worry too much... however, I never let my ski sit for more than 2 weeks without starting it up and reving it a few times even during the months I'm using it. I think it keeps the fuel system functioning as well as re-lubricating all the internal parts and blowing moisture out the exhaust system. Seems to me, spraying fogging oil down the intakes would eventually cause build up on the valves. Lucky for me winters are warm here and all I plan on doing is to start mine up every week or so (without garden hose) and give it a few revs.... I think I would do it if I lived up north too. If I owned a motorcycle up north, I wouldn't allow it to sit all winter without running it either. Since knowing waveruunners have water running in the exhaust system, I would never let them sit too long without running them. By running them for a very short time every two weeks, the advantages are: Keeping the carbs/ fuel system fuctioning, spreading lubrication inside the engine, and blowing moisture out the exhaust system. But what do I know, this works for me...:emoticont

Re: winterizing yamaha FX140

I ride in salt water only,and flush my ski's for 3-4 minutes max.And have had my motors apart and never found much deposits of salt or sand.IMO,flushing longer than that is useless,other than hearing your motor run.I also stay off of the throttle while flushing,just little half throttle pulls towards the end of my flush,then a couple more after the water is turned off.Then the next day start it for a few seconds and a couple half throttle revs.Thats how I do mine,and consider it to be very cleaned out when done.I also do the WD40 spray down every once in awhile.

I also do about the same as mentioned above,by not winterizing.But I ride most of the winter anyways...we only get cold snaps here that last a few days.Even if I ride slow to stay dry,its still worth getting out on the water...for me anyways.

On the antifreeze issue...unless you have a water jacket that is 'full' of water,there is no risk of breaking anything due to expansion of water when it freezes.Apperantly,Yamaha designs thier cooling systems better than Seadoo.
